Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
A system for insulating attics wherein access to the attic is had through an opening in the floor of the attic, which opening is normally closed by a trap door, comprising: (a) an adjustably expandable guard, said guard being adjustable to a size and shape corresponding to the size and shape of said opening; (b) means for securing said guard in surrounding and upwardly extending relation to said opening; and (c) a trap door insulating pack comprising a harness enclosing one or more layers of insulating material, said pack being attachable to said trap door such that said pack overlies essentially all said trap door.
Claim 2
Independent Claim
105 words
A system for insulating attics wherein access to the attic is had through an opening in the floor of the attic, which opening is normally closed by a trap door, comprising: (a) an adjustably expandable guard, said guard being adjustable to a size and shape corresponding to the size and shape of said opening; (b) means for securing said guard in surrounding and upwardly extending relation to said opening; and (c) a trap door insulating pack comprising a harness enclosing one or more layers of insulating material, said pack being attachable to said trap door such that said pack overlies essentially all said trap door.
Claim 3
Dependent Claim
33 words
A system for insulating attics according to claim 1, wherein said adjustably expandable guard comprises a plurality of interconnected panels, each of said panels being adjustably positionable with respect to each adjacent panel.
Claim 4
Dependent Claim
67 words
A system for insulating attics according to claim 1, wherein said expandable guard comprises four generally rectangular interconnected members, each of said members comprising a first panel and a second panel, each of said first panels being attached to the second panel of an adjacent member such that said first panel of said member is slideably positionable with respect to said second panel of said adjacent member.
Claim 5
Dependent Claim
80 words
A system for insulating attics according to claim 1, wherein said expandable guard comprises four generally interconnected members, each of said members comprising a first panel and second panel joined along a common line, wherein each of said second panels defines a generally horizontally slot and wherein each of said members is slideably attached to an adjacent member by a rivet extending through said slot in said member's second panel and affixed to said first panel of said adjacent member.
Claim 6
Independent Claim
133 words
A system for insulating attics wherein access to the attic is had through an opening in the floor of the attic normally closed by a trap door, comprising: (a) four generally rectagular interconnected members, each of said members comprising a first panel and a second panel, each of said panels being attached to the second panel of an adjacent member such that said first panel of said member is slideably positionably with respect to said second panel of said adjacent member; (b) means for securing said members in surrounding and upwardly extending relationship to said opening; and (c) a trap door insulating pack comprising a harness enclosing one or more layers of insulating material, said pack being attachable to said trap door such that said pack overlays essentially all of said trap door.
Claim 7
Independent Claim
133 words
A system for insulating attics wherein access to the attic is had through an opening in the floor of the attic normally closed by a trap door, comprising: (a) four generally rectagular interconnected members, each of said members comprising a first panel and a second panel, each of said panels being attached to the second panel of an adjacent member such that said first panel of said member is slideably positionably with respect to said second panel of said adjacent member; (b) means for securing said members in surrounding and upwardly extending relationship to said opening; and (c) a trap door insulating pack comprising a harness enclosing one or more layers of insulating material, said pack being attachable to said trap door such that said pack overlays essentially all of said trap door.
Claim 8
Independent Claim
153 words
A system for insulating attics wherein access to the attic is had through an opening in the floor of the attic normally closed by a trap door, comprising: (a) four generally rectangulr interconnected members, each of said members comprising a first panel and second panel joined along a common line, wherein each of said second panels defines a generally horizontal slot and wherein each of said members are slideably attached to adjacent members by a rivet extending through said slot in said member's second panel and affixed to said first panel of said adjacent member, and wherein each of either of said first panels or said second panels defines an outwardly extended flange along its bottom edge; and (b) a trap door insulating pack comprising a harness enclosing one or more layers of insulating material, said pack being attached to said trap door such that said pack overlies essentially all said trap door.
Claim 9
Independent Claim
153 words
